| Resumo: |
Sildenafil is widely used for the treatment of erectile dysfunction with few studies are available on the protective role of propolis against its reproductive toxicity. The present study aims to investigate the hormonal biochemical and histomorphometric alterations induced in the testicular tissues by sildenafil overdoses. Four groups of rabbits were exposed to sildenafil with or without propolis as follows: Group I received the formulated vehicle, Group II received sildenafil (3 mg/kg), Group III received propolis (50 mg/kg), Group IV received sildenafil plus propolis. Sildenafil lowered body weight gain, testosterone and follicular stimulating hormone concentration but increased testis index while luteinizing hormone was almost not affected. Moreover, sildenafil treated rabbits showed degenerative seminiferous tubules and disturbance of spermatogenesis together with spermatocytes sloughing and nuclear alterations. Exposure to sildenafil plus propolis ameliorated tubular alterations, spermatogenesis disturbances, hormonal levels changes and partially protected spermatocytes from morphological nuclear alterations but could not ameliorate the effect on the body weight gain and testis index. The findings of the present work may indicate that propolis can ameliorate partially the reproductive toxicity induced by sildenafil overdoses with more need for further studies on the adverse effect of these doses on the other vital organs.
